See where your
browsing takes you

Capsule is a browser extension that turns your browsing into an interactive graph. See connections between pages, discover patterns with AI clustering, and never lose track of a rabbit hole again.

How it works

Capsule runs quietly in the background. Every page you visit becomes a node, and connections form automatically as you browse.

Graph visualization

Every tab and link becomes a node in an interactive force-directed graph. See your entire browsing session at a glance.

AI clustering

AI groups related pages into clusters automatically — research topics, shopping, work projects — without any manual tagging.

Session history

Every browsing session is saved. Search across sessions with natural language and find that page you visited last week.

Knowledge synthesis

After a session, export your entire research as a structured markdown document — with AI-written summaries per topic and all sources linked.

AI synthesis

Turn any rabbit hole into a structured document

After a session, Capsule reads every page you visited and generates a structured research document — clustered by topic, summarised by AI, with every source linked. Paste it into any note-taking app that speaks Markdown.

  • AI-written summary for each topic cluster
  • Every page linked with title and URL
  • Internal links between related pages
  • One click from the extension
